Built-In Lock Prevents Theft
Many drainage pits are located on main roads and factory grounds. These areas are often unguarded, making covers vulnerable to theft.
Thieves may remove covers and sell them as scrap metal. This creates financial losses and increases safety risks caused by open drainage pits.
Our Lockable Drain Cover features a built-in locking core. A dedicated tool is required for opening. Unauthorized removal is prevented without the correct opening tool.
This design provides effective theft protection and reliable safety for drainage systems in remote or unmonitored areas.
Reliable Lock Performance Outdoors
We designed the locking system for demanding outdoor conditions.
The lock core provides strong rust resistance, while internal components are protected against water and dust. It continues to operate reliably after long-term exposure to rain, dirt, and changing weather conditions.
We test the lock under salt spray and high-temperature conditions to ensure stable performance in different climates.
The opening tool is simple to use. Maintenance workers only need one dedicated opening tool to operate each unit quickly and efficiently.
Four Load Grades with One Lock System
This lockable drain cover is available in four load grades: light, standard, heavy, and extra heavy.
All models have a diameter of Φ700 and overall dimensions of 380 by 680 millimeters. All models meet the D400 load rating with a capacity of 400 kN.
The differences are mainly in wall thickness and internal rib structure. The light grade is suitable for sidewalks and green areas, while the extra heavy grade is designed for freight roads, industrial zones, and port areas.
The same locking system fits all grades, so customers only need one set of opening tools for the entire project.
Strict Lock Function Testing
Our product is widely used in projects requiring additional security protection.
We invest in dedicated mold development and production process improvements. We check the lock hole position on every unit and verify that each locking system is installed correctly.
Before shipment, every production batch undergoes lock function testing. We ensure that each lock operates smoothly and provides secure locking performance.
We maintain stock availability for all four grades. Orders are shipped within 6 to 15 days.
We use steel pallets for export packaging and support mixed models in one container.
